Abstract
This paper presents a method for determining the boundary criterion for the rock deformation zone in the rock mass above a tunnel under construction when using two-layer calculation schemes in forecasts of earth surface deformations. The method is applied to the conditions of construction of tunnels of the St. Petersburg subway system.
